A phthalimide-fused naphthalene diimde (NDIIC24) with a low-lying LUMO energy level (−4.21 eV) and moderate solubility was synthesized. Organic field effect transistors (OFETs) based on solution processed thin films showed typical n-channel characteristics with a high electron mobility of 0.056 cm2 V−1 s−1 and a high on–off current ratio of 105–106. The devices exhibited very good air stability and operating stability. Complementary inverters based on n-type NDIIC24 and p-type TIPS–pentacene demonstrated a maximum voltage gain (−dVOUT/dVIN) of 64.

A series of linear and star-shaped pyrazine-containing acene molecules 1a–b, 2a–b and 3 substituted by dicarboximide groups are synthesized via condensation reactions between o-diamine and dione. High electron affinity (up to 4.01 eV) is achieved due to the introduction of an electron-deficient pyrazine moiety and the attachment of electron-withdrawing dicarboximide groups. Some of these molecules show thermal liquid crystalline behavior and their space-charge limited current mobilities are measured. The high electron affinity and liquid crystalline property qualify them as promising electron transporting materials in organic optoelectronic devices.

A series of unsymmetricalnaphthaleneimide derivatives (1a, 1b, 2, 3, 4, 5) with high electron affinity was synthesized and used in n‐channel organic field‐effect transistors (OFETs). They have very good solubility in common organic solvents and good thermal stability up to 320 °C. Their photophysical, electrochemical, and thermal properties were investigated in detail. They showed low‐lying LUMO
